Infrastructure & Cloud Security Engineer
Engineers in this role design and implement security controls across GPU compute clusters, multi-cloud environments, and distributed infrastructure that power AI platforms. They work hands-on with Kubernetes, networking, identity systems, and CI/CD pipelines to establish Zero Trust principles and secure model weights, inference endpoints, and customer data at scale. What distinguishes this work is the focus on protecting specialized AI workloads—from GPU execution environments to model deployment systems—while enabling rapid infrastructure scaling. These engineers typically sit within dedicated security teams reporting to the CISO, partnering closely with platform, infrastructure, and ML engineering teams to shift security left and make secure-by-default systems the easiest path for developers.

This role is advertised at 3 levels, so a single figure for the role would describe none of them. Experience and pay are the midpoints for each level on its own.
| Level | Share | Median years | Median pay |
|---|---|---|---|
| Mid | 41%(16) | — | — |
| Senior | 31%(12) | 5 | — |
| Staff / Principal | 28%(11) | 8.5 | — |
A dash means too few postings stated it to report a midpoint. Most companies do not publish a salary band, so pay is indicative rather than a market rate.
“engineers who work inside AI-assisted tooling every day”
“Build security for large-scale AI clusters, implementing robust cloud security architecture”
“constantly think about how to operate securely with the introduction of new technologies (OS-level, AI coding agents, etc.)”
“use approved AI coding tools, such as Claude Code, to accelerate scripting, testing, documentation, and security automation”
Requirements are a share of every open posting, so a role missing from this list is one where almost nobody asks. Work mode is different: many postings never say, so that figure counts only the ones that do.
